In this paper we thoroughly cover the issue of blank nodes, which have been defined in RDF as "existential variables". We first introduce the theoretical precedent for existential blank nodes from first order logic and incomplete Information in database theory. We then cover the different (and sometimes incompatible) treatment of blank nodes across the W3C stack of RDF-related standards. We present an empirical survey of the blank nodes present in a large sample of RDF data published on the Web (the BTC-2012 dataset), where we find that 25.7% of unique RDF terms are blank nodes, that 44.9% of documents and 66.2% of domains featured use of at least one blank node, and that aside from one Linked Data domain whose RDF data contains many "blank node cycles", the vast majority of blank nodes form tree structures that are efficient to compute simple entailment over. With respect to the RDF-merge of the full data, we show that 6.1% of blank-nodes are redundant under simple entailment. The vast majority of non-lean cases are isomorphisms resulting from multiple blank nodes with no discriminating information being given within an RDF document or documents being duplicated in multiple Web locations. Although simple entailment is NP-complete and leanness-checking is coNP-complete, in computing this latter result, we demonstrate that in practice, real-world RDF graphs are sufficiently "rich" in ground information for problematic cases to be avoided by non-naive algorithms.

M.A. (Clinical Psychology) / This study explores the Western ideal of the thin body as experienced by Black female students. This research was motivated by the limited number of empirical studies that employ a qualitative method to investigate Black South African females’ perception of the thin ideal, or what they perceive an ideal body to be. Three Black female students were recruited from the University of Johannesburg’s campus, to participate in the interviews. On campus, interaction is encouraged through an initiation process where everyone is invited to take part, and where diversity is celebrated. This setting was appropriate because the students found themselves in a socio-cultural flux between traditional values and values instilled by modern western society. Data collection and the analysis were guided by a phenomenological research design, namely, Interpretative Phenomenological Analysis (IPA) because it explores the participants’ experience of the Western thin ideal from their perspective, and acknowledges the researcher’s enmeshed interpretation of the participants’ worldview. The study resulted in the identification of four master themes: 1) Physical presentation, 2) The environments influence on my body image, 3) Sense of worth, and 4) Admiration versus animosity, which were discussed in relation to relevant literature. In the concluding chapter, the key strengths and limitations of this study are reviewed, and the implications of the findings for further investigation are discussed...

The aim of this work is to determine a methodology to measure the leanness level of the organizations that have an internship in the framework of the minor specialization of Quality Management and Lean Six Sigma at University of Economics.

The field of treating and learning about eating disorders in athletes is a growing field that continues to flourish as more knowledge is acquired. The purpose of this study is to examine the influence that length of time in the sport, age at which an individual starts a competitive sport, level of competitiveness, and type of sport (leanness vs. non-leanness focused) has on disordered eating behaviors. The participants were college students who were involved in at least one competitive sport in their life. They completed the EAT-26 questionnaire as well as a basic questionnaire. There was not enough data collected to conduct a logistic regression so descriptive statistics are reported. This remains an area to be further explored as there is a gap in the literature on the age at which individuals begin competitive sports and the length of time in sports and how that relates to disordered eating behaviors.

The implementation of lean manufacturing concepts has shown significant impacts on various industries. Numerous tools and techniques have been developed to tackle specific problems in order to eliminate wastes and carry out lean concepts. With the focus on "how to make a system leaner," little effort has been made on determining "how lean the system is." Lean assessment surveys evaluate the current status of a system qualitatively against predefined lean indicators. Lean metrics are developed to quantify performance of improvement initiatives, but each metric only focuses on one specific area. Value Stream Maps demonstrate the current and future states graphically with the emphasis on time-based performance only. A truly quantitative and synthesized measure for overall leanness has not been established. In some circumstances, being lean may not be the only goal for manufacturers. In order to compete in the rapidly changing marketplace, manufacturing systems should also be agile to respond quickly to uncertain demands. Nevertheless, being extremely agile may increase the cost of regular operations and reduce the leanness of the system. Similarly, being extremely lean may reduce flexibility and lower the agility level. Therefore, a manufacturing system should be agile enough to handle the uncertainty of demands and meanwhile be lean enough to deliver goods with competitive prices and lead time. In order to achieve the appropriate leanness level, a leanness measure is needed to address not only "how lean the system is" but also "how lean it should be." In this research, a methodology is proposed to quantitatively measure leanness level of manufacturing systems using the Data Envelopment Analysis (DEA) technique. The production process of each work piece is defined as a Decision Making Unit (DMU) that transforms inputs of Cost and Time into output Value. Using a Slacks-Based Measure (SBM) model, the DEA-Leanness Measure is developed to quantify the leanness level of each DMU by comparing the DMU against the frontier of leanness. A Cost-Time-Value analysis is developed to create virtual DMUs to push the frontier towards ideal leanness so that an effective benchmark can be established. The DEA-Leanness Measure provides a unit-invariant leanness score valued between 0 and 1, which is an indication of "how lean the system is" and also "how much leaner the system can be." With the help of Cost-Time Profiling technique, directions of potential improvement can be identified by comparing the profiles of DMUs with different leanness scores. The leanness measure can also be weighted between Cost, Time and Value variables. The weighted DEA-Leanness Measure provides a way to evaluate the impacts of improvement initiatives with an emphasis on the company's strategic focus. Performing the DEA-Leanness measurement requires detailed cost and time data. A Web-Based Kanban is developed to facilitate automated data collection and real-time performance analysis. In some circumstances where detailed data is not readily available but a Value Stream Maps (VSM) has been constructed, the applications of DEA-Leanness Measure based on existing VSM are explored. Besides pursuing leanness, satisfying a customer's demand pattern requires certain level of agility. Based on the DEA-Leanness Measure, appropriate leanness targets can be identified for manufacturing systems considering sufficient agility level. The Online-Delay and Offline-Delay Targets are determined to represent the minimum acceptable delays considering inevitable waste within and beyond a manufacturing system. Combining the two targets, a Lean-Agile Performance Index can then be derived to evaluate if the system has achieved an appropriate level of leanness with sufficient agility for meeting the customers' demand. Hypothetical cases mimicking real manufacturing systems are developed to verify the proposed methodologies. An Excel-based DEA-Leanness Solver and a Web-Kanban System have been developed to solve the mathematical models and to substantiate potential applications of the leanness measure in real world. Finally, future research directions are suggested to further enhance the results of this research. / Ph. D.

This thesis is focused on frailty in old age. The frailty syndrome is the newest geriatric syndrome and can be aptly called the ultimate geriatric syndrome due to the complexity of its causes and the wide range of adverse outcomes it may lead to in older persons. Several of the important correlates of frailty, namely falls, underweight and sarcopenia, are discussed in the context of their relationship with frailty. These entities are geriatric syndromes in their own rights, sharing many common risk factors and arriving at adverse health outcomes either directly or via the pathway of frailty. In the publications that arose from this work, the risk factors of falls, in particular the relationship between medications and chronic diseases in causing falls; risk factors and outcomes of sarcopenia, in particular its relation to diabetes mellitus and other chronic diseases; and how underweight poses survival risks in both community-living and institutionalized older people, are discussed. The final publication of this series of studies demonstrated the reversibility of the frailty syndrome, showing that not all who were in the pre-frailty stage will decline. Risk factors associated with improvement or decline in the pre-frail stage were identified in the local population, and a period of relative stability opened for possible interventions was observed. This thesis thus examines the complex interplay of these syndromes in old age. It is hoped that these publications will enable further research into the underlying mechanisms of frailty and to elucidate modifiable risk factors, hence enabling older people, in particular those in the pre-frail stage, to live healthier and longer lives. / Lee Shun Wah Jenny. / Thesis (M.D.)--Chinese University of Hong Kong, 2015. / Includes bibliographical references. / Title from PDF title page (viewed on 15, September, 2016).
